R help - Dec 2012 - Solving a multinomial gompertz partial differential equation in r

I haven't used r in quite a while but would like to get back into it. I
have a problem that I would like to solve with r. I have some multinomial
data that looks to follow an asymmetric sigmoidal growth pattern. Solving
a multinomial gompertz partial differential equation in r is what I’m after.
Would anyone be able to provide me the code and packages to do something
like this?

Hi Brandon,

You can try ReacTran package:

cran.r-project.org/web/packages/ReacTran/vignettes/PDE.pdf

Best,
-m

ReacTran is for managing the tr5ansport in reactive transport models, is 
relies on package deSolve that contains the ODE/PDE solvers, so I would 
recommend to start with this first.

Papers, slides and tutorials with full source code can be found at:

http://desolve.r-forge.r-project.org

... and an overview about packages dealing with differential equations 
can be found in the Taskview:

Hope it helps
